This invention concerns improvements in or relating to the apparatus for collecting cigarettes from cigarette-making machines, and in particular an improved method of, and apparatus for, automatically collecting cigarette into receptacles as the cigarettes issue from a cigarette making machine. An object of the invention is to provide a high degree of automaticity and continuity in the supply of empty receptacles to receive cigarettes from a cigarette making machine, the collection of cigarettes into such receptacles, and the removal of the receptacles when filled.

According to the present invention there is provided a method of automatically collecting cigarettes into receptacles as the cigarettes issue from a cigarette making machine, wherein empty receptacles are conveyed sideways in succession by conveying means from which they are successively removed lengthwise and subsequently displaced laterally and moved in a reverse direction so as to pass lengthwise in succession past a filling station towards and on to the said conveying means, in such a manner that empty receptacles removed from the said conveying means are subsequently replaced by filled receptacles, said receptacles when filled being moved sideways from the filling station by the said conveying means. The receptacles may be'conveyed by conveyingmeans comprising transporter vehicles, which for convenience will be referred to herein and in the appended claims as trucks.

Further according to the invention there is provided apparatus for carrying out the method referred to above, comprising a truck or a train of trucks arranged to move (e. g. intermittently) pasta cigarette machine and adapted to carry receptacles placed side by side thereon, a filling position at which cigarettes are automatically fed into said receptacles, means for automatically removing an empty receptacle from the truck or a truck and subsequently displacing said receptacle into a position from which it can be moved lengthwise past the said filling position, mean to move'the receptacle automatically lengthwise past the filling position and on to the truck, and control means to control the movement of the truck or trucks. The arrangement may be such that while a filled receptacle is being moved on to a truck an empty receptacle is removed from a truck the truck or train of trucks remaining stationary during said operations and moving on when they are completed. The means to remove receptacles from trucks may comprise an endless chain conveyor having a pawl adapted to engage a part of a receptacle said endless chain conveyor being driven in timed relationship with the movement of the trucks. The floor of the truck or trucks may have a width less than the length of a re ceptacle. The truck may be provided on three sides thereof with upright guard members or walls so disposed as to maintain in correct position receptacles carried by the truck.

One arrangement made in accordance with the invention will now be described by way of example with reference to the accompanying drawings which show collecting mechanism for collecting cigarettes as they issue from a continuous rod type cigarette making machine.

In the drawings:

Figure 1 is a small scale plan view of the essential parts of the apparatus shown attached to the delivery end of a continuous rod cigarette mak ng machine.

Figure 2 is a front elevation of Figure 1 and also shows a receptacle on the apparatus.

Figures 3A and 3B together constitute a plan view to a larger scale of a conveyor platform shown in Figure 1.

Figures 4A and 43 together constitute a front elevation of Figures 3A and 3B and also show to a larger scale, and in more detail, parts shown in Figure 1.

Figure 5 is an elevation looking at the righthand end of Figure 1.

Figure 6 is a sectional end elevation, looking at the right-hand end of Figure 1, and shows driving mechanism and a gear box.

Figure 7 is a sectional plan of the gear box shown in Figure 6.

Figure 8 is a plan view of the left-hand end of Figure l the view being taken below the conveyor platform and showing mechanism hidden in Figure 1.

Figure 9 is a fragmentary view looking at the right-hand of Figure 8.

Figure. 10 is a front elevation of some of the mechanism shown at the left-hand end of Figure 8, parts being broken away to show inner parts.

Figure 11 is a fragmentary view of some parts of Figure 10, looking from the right-hand of that figure.

Figure 12 is a sectional plan of a gear box shown at the right-hand end of Figure 3B and in elevation in Figures 4B and 5.
